Once the Hairgrass becomes super dense, you'll see the tank transform again, Hairgrass is in my top 5 fav Aquarium plants, one I have great experience with. As for the Hygro, looking a little pale, I understand you are aiming for low tech, but it looks like it needs a tiny touch Fe (Iron) and maybe a little more light to bring out it's true beauty.

Whelp, after moving my aquarium to a different room I have destroyed the original carpeted and healthy ascetic by allowing too much ambient sunlight and not cleaning anything. Algae takeover! It's not worth photographing, but I will be rescaping this aquarium into a dual-island aquascape soon when I get my plan organized.
